Settings

Setting up ConfigModule to use ConfigFsLoader

If you provide application settings using a JSON file (on the server platform), you can call the forRoot static method using the ConfigFsLoader. By default, it is configured to retrieve application settings from the path /config.json (if not specified).

You can customize this behavior (and ofc other settings) by supplying a file path to ConfigFsLoader.

• Import ConfigModule using the mapping '@ngx-config/core' and append ConfigModule.forRoot({...}) within the imports property of app.module.
• Import ConfigFsLoader using the mapping '@ngx-config/fs-loader'.

Note: Considering the app.module is the core module in Angular application.

config.json

{
  "system": {
    "applicationName": "Mighty Mouse",
    "applicationUrl": "http://localhost:8000"
  },
  "seo": {
    "pageTitle": "Tweeting bird"
  },
  "i18n":{
    "locale": "en"
  }
}

app.module.ts

...
import { ConfigModule, ConfigLoader } from '@ngx-config/core';
import { ConfigFsLoader } from '@ngx-config/fs-loader';
...

export function configFactory(): ConfigLoader {
  return new ConfigFsLoader('./public/assets/config.json'); // FILE PATH
}

@NgModule({
  declarations: [
    AppComponent,
    ...
  ],
  ...
  imports: [
    ConfigModule.forRoot({
      provide: ConfigLoader,
      useFactory: (configFactory)
    }),
    ...
  ],
  ...
  bootstrap: [AppComponent]
})

ConfigFsLoader has one parameter:

• path: string : path to JSON file, to retrieve application settings from (by default, config.json)

:+1: Well! @ngx-config/fs-loader will now provide application settings to @ngx-config/core using fs.
